Is possible to have sequential content?

Hi.
My customer need the next functionality. This functionality is present in WhishList for Wordpress. I am a Joomla! lover, but maybe is time to move to Wordpress for some sites.

if you buy a suscription today, you have access to article 1. Then in a week, you have access to Article 2, too. Then the next week you have access to Article 3, and then...

All content is created previously, and depending of the date of suscription the content is delivered.

This is for courses. You receive the lesson 1, and the next week you receive the lesson 2, etc. But every student can buy the course in different date.

I believe you can do this using a combination of CBSubs and Professional incubator projects.

You could use CBSubs CB Field integration to populate a CB Field containing the subscription activation date.

Then you can use the CB Content bot plugin to filter article content so that the actual body of the article will only appear when X days or more pass from subscription activation.
